Sofia Richie did not dissapoint for her 21st birthday, as she took off in a private jet to Las Vegas to have parties at both the day club and the night club.=
The model then boarded a private jet with her girlfriends, and Lord Disick, and flew to Sin City.
The party kicked off at the Wynn Hotel and Casino at one of the hottest pool parties in town, Encore Beach Club.
The pool party featured DJ Alesso and Richie's VIP section included life-size cardboard cutouts of the model, and even pillows with photos of her beloved dog, Hershela.
Sofia arrived rocking an orange bikini for the bash, and danced with her crew behind the DJ booth.
For dinner, Sofia and her entourage, including Kylie Jenner, dined at Cipriani Las Vegas in Wynn Plaza and got to enjoy her first legal drink of alcohol during a champagne birthday toast with Perrier-Jouët.
The last round of partying took place at XS nightclub where Sofia was again welcomed by signs and also treated to a performance by The Chainsmokers.
We're told at one point, Drew Taggart, from The Chainsmokers, had Sofia join him on stage and had the entire venue sing "Happy Birthday."
Sofia ended up hanging out on stage with her girls dancing, jumping around and taking shots with the duo, who currently have a residency with Wynn Nightlife.
If you think the party crashed in some gigantic hotel room, you would be wrong. Instead, the party gassed up the private jet and flew home at 4 AM.
You can imagine what that flight was like, Richie posted video on Instagram of the girls spilling into the airplane.
Bottom line: That's how you do Vegas when you're a 21-year-old millionaire ... with billionaire friends.
